Cable systems and test trials with cable modems in Slovenia

Abstract

In Slovenia we have over 100 cable networks with approximately 220,000 cable connections. Some networks are in the reconstruction phase-topology of the system is transformed, the frequency band of networks is being increased, while the networks are being enabled for two-way communication. Several pilot projects are being carried out in Slovenia. An innovative technical solution for the cable modems was found. For these modems amplitude shift keying modulation was used. The speed is 1.25 Mbps and the frequency band is 6 MHz in each direction. At the present network load, users can reach transfer rate up to 750 kbps. The second pilot project is underway in Maribor, second biggest city in Slovenia. It is a tree topology system and has over 10,000 connections. At the moment, individual branches for enabling two-way communication are being brought up to date, at the same time domestic equipment and the equipment of different manufacturers is being tested.
